Supplement 3 Variables Derived from the Student, Home, Teacher, and School Questionnaire Data

Overview

This supplement contains documentation on all the derived variables contained in the PIRLS and prePIRLS 2011 data files that are based on background questionnaire variables. These variables were used to report background data in the PIRLS 2011 International Results in Reading report, and are made available as part of this database to be used in secondary analyses. This supplement has four sections corresponding to each background questionnaire from which reporting variables are derived.

Section 1: Student Questionnaire

Section 2: Home Questionnaire (Learning to Read Survey)

Section 3: Teacher Questionnaire

Section 4: School Questionnaire

The following information is provided for each derived variable:

Derived Variable Name

Variable Label

Title of International Report Exhibit

Report Location

A procedural description of how the derived variable was computed, including missing data rules if different from the general missing data rule described below

Information about whether the variable was available in the previous cycle


Derived Variable Naming Convention

The derived variables are named according to the variable-naming convention in the PIRLS 2011 international database (see Chapter 4).

Variable Naming Convention

Data Source

ASDG*** Variables derived from student background data

ASDH*** Variables derived from home background data

ATDG*** Variables derived from teacher background data

ACDG*** Variables derived from school background data

Missing Rule for Derived Variables

When calculating derived variables, students were only included if they had valid responses for at least 2/3 of the source variables. Students who did not have responses for 2/3 of the source variables were considered missing for the derived variable.
